python - java.lang.ClassNotFoundException: com.johnsnowlabs.nlp.DocumentAssembler spark in Pycharm with conda env

Question

I saved a pre-trained model from spark-nlp, then I'm trying to run a Python script in Pycharm with anaconda env:

Model_path = "./xxx"
model = PipelineModel.load(Model_path)

But I got the following error: (I tried with pyspark 2.4.4 & spark-nlp2.4.4, and pyspark 2.4.4 & spark-nlp2.5.4) Got the same error:

21/02/05 13:31:21 WARN NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

Traceback (most recent call last):

I'm new to pyspark and spark-nlp, might someone be able to help please?
